However, since this cap is separated from the socket, it is easy to lose after removing the cap at the time of use. If lost and left as it is, as described above, there is a high possibility that a predetermined optical signal cannot be transmitted due to contamination of the optical element. In other words, a malfunction may occur, and the reliability of the socket of the optical connector is reduced.

On the other hand, in the insertion hole of the socket,
Even when the plug of the optical connector is not inserted, that is, when there is no need to transmit a signal, when the power of the device provided with the socket of the optical connector is turned on, the optical element of the socket of the optical connector is always turned on. It was operating. Therefore, the life of the optical element, and thus the life of the socket, has been greatly reduced. As a result, even if the degree of contamination of the optical element is relatively small, it is easy to make it impossible to transmit a predetermined optical signal. Therefore, also from this point, the reliability of the socket of the optical connector has been lowered.

Further, when the power supply of the device is turned on, the optical element is always in an operating state, so that the power consumption of the entire device is undesirably increased.

An object of the present invention is to provide an optical connector socket capable of maintaining high reliability of the optical connector socket.

A projection 213 having a through hole 214 for holding 0 is provided. The elastic body 230 is fitted into the shaft 240 (see FIG. 11). Both ends of the shaft portion 240 are inserted into elongated holes 227W1 and 227W2 as a guide mechanism, and also function as a guide mechanism.

The method of assembling the optical connector socket 200W according to the second embodiment of the present invention thus configured is substantially the same as that of the optical connector socket 200 according to the first embodiment of the present invention. The description is omitted.

Next, the mechanism operation of the socket 200W will be described. In the socket 200W, when the plug 100 is not inserted, the shutter portions 210W1 and 210W2 are urged toward the entrance side of the insertion hole 220W by the elastic members 230 and 230, so that the entrance side of the insertion hole 220W is the shutter portion 210W1. , 210W2 (the state of FIG. 10A).

At the position shown in FIG. 10B, as shown in FIG. 10C, the plug 100 is inserted into the insertion hole 220W.
When the insertion starts with a force equal to or greater than the urging force of the elastic members 230, 230, the front surfaces of the shutters 210W1, 210W2 are pressed by the plug tip 159 of the plug 100, and the shutters 210W1, 210W2 are rotated. The tip side enters the inside of the insertion hole 220.

And

The shutter section 210S is formed in a substantially square shape when viewed from the front. The width dimension and the vertical dimension of the shutter section 210S are the same as the shutter section 210 of the socket 200 of the optical connector according to the first embodiment of the present invention. The shutter portion 210S has a groove portion 217S that engages with the convex portion 240S from one end to the vicinity of the other end in the longitudinal direction of both side surfaces.

The shutter portion 210S has a hook recess 219S for manually moving the shutter portion 210S at the upper portion on the front side. The shutter portion 210S has a positioning concave portion (not shown) on the front side into which the positioning convex portion 151b above the engaging convex portion 150 of the plug 100 is fitted.

Thereafter, the grooves 217S and 217S may be fitted into the protrusions 240S and 240S while pulling the shutter 210S forward.

The shutter unit 210 set as described above
S is rotated vertically while sliding to the front side, and the convex extending portion 218S of the shutter portion 210S is engaged with the entrance side concave portion 224S, so that the entrance side of the insertion hole portion 220S is moved by the shutter portion 210S. It will be almost blocked.

When the plug 100 is to be inserted into the insertion hole 220S, the shutter 210S is pivoted forward while sliding upward from the above state, and after being leveled,
When it is slid to the rear and pushed in, the shutter 210S
Is fitted into the rear recess 225S1. Therefore, the shutter 210S is stored horizontally in the space 225S. Thus, the plug 100 can be inserted into the insertion hole 220S.
After that, the plug 100 may be inserted into the insertion hole 220S by a press fit.

In the plug 100 which has been completely inserted into the insertion hole 220S, the plug tip 159 is
It is held at 0. The distal end surface of the plug distal end portion 159 is located a predetermined minute distance before the front surface of the optical element (not shown). In addition, the engagement convex body 151 is
It is held by the surfaces from both side surfaces to the bottom surface of the insertion hole 220 and the front surface of the shutter 210S. However, the magnitude of the holding force by the front surface of the shutter portion 210S depends on the frictional force between the shutter portion 210S and the ceiling surface above the space 225S, and therefore the first embodiment of the present invention. Is smaller than the holding force of the shutter portion 210 of the socket 200 of the optical connector according to the above.

(See FIG. 6), the lower positioning projection 151b is
It is inserted into the positioning through hole 223, while the upper positioning projection 151b is inserted into a not-shown positioning recess of the shutter 210S. As a result, the plug 100 is held by a holding force relatively close to that of a general EIAJ standard socket.

Conversely, when the plug 100 is pulled out of the insertion hole 220, the upper positioning projection 151b is fitted into the positioning recess (not shown) of the shutter 210S. Part 21
0S is also slid to the front and pushed back. The pushed-back shutter portion 210S is rotated to be vertical while sliding as shown in FIG. 12, and the convex extending portion 218S of the shutter portion 210S is engaged with the entrance-side concave portion 224S.
As a result, the shutter 210S is inserted into the insertion hole 220
At the inlet side of S, the state is returned to a predetermined substantially closed state. By the way, in the socket 200S, the rear side concave portion 225S1 as the rear side engaging portion and the entrance side concave portion 224S as the entrance side engaging portion are not concave portions but convex portions, and the convex portions of the shutter portion 210S are correspondingly formed. It goes without saying that the extension 218S may be a recess.

If the mounted state can be set, as described above, the first housing portion 205CM 'may not be able to hold most of the mounted shutter portion 210C' when viewed from the front.

Next, an optical connector using a magnet in place of the elastic member will be described as a socket of an optical connector according to a tenth embodiment of the present invention with reference to FIG. FIG. 29 is a sectional view showing the socket of the optical connector according to the tenth embodiment of the present invention.

A socket 200G of the optical connector according to the tenth embodiment of the present invention is substantially the same as the socket 200 'of the optical connector according to the eighth embodiment of the present invention. Elastic part 2 used in
30A 'is removed and replaced with magnets 230G1, 2
30G2 were provided at two places described later.

The magnet 230G1 is embedded on the back side of the shutter 210G. The shutter 210G
Is substantially the same as the shutter portion 210 'of the socket 200', except that the magnet 230G1 is buried, and that the magnet 230G1 is not provided because a concave portion for setting the elastic portion is unnecessary.

The magnet 230G2 is inserted into the insertion hole 220G (not shown).
Space 225)
G (similar to the space 225 'of the socket 200') and the housing portion 205G facing the shutter portion 210G (substantially the same as the housing portion 205 'of the socket 200', but with the first housing portion). Second
The boundary with the housing is not shown. ) Is buried so as to face the magnet 230G1.

The magnet 23 provided in the shutter 210G

0G2 may be provided so as to be repelled. Therefore, for example, the S pole (or N pole) of the magnet 230G1 is provided toward the back side of the shutter 210G,
The south pole (or north pole) of G2 may be provided on the upper surface of the insertion hole 220G of the housing 205G so as to face downward.

The magnet 230G1 is provided relatively on the upper side of the shutter 210G, that is, closer to the shaft 240G (the same as the shaft 240 'of the socket 200'). When the shutter 210G is provided on the upper side in this way, the insertion hole 2
Even at the entrance of 20G (ie, when the magnet 230G1 is farthest from the magnet 230G2), the magnet 230G1 provided in the shutter 210G and the magnet 230G2 provided in the housing 205G are relatively close to each other and This is because they oppose each other to repel each other. That is, in the entire moving range of the shutter 210G, the urging force of the shutter 210G toward the entrance of the insertion hole 220G can be increased.

The assembly of the socket 200G is substantially the same as that of the socket 200 ', and the description thereof is omitted.

The mechanical operation of the socket 200G is substantially the same as that of the socket 200 '(ie, substantially the same as the socket 200). The only difference is whether the urging force is due to the elastic member or the repulsive force of the magnet.

By the way, the sockets 200, 200 'and the like of the optical connector described above are generally
00, 200 'and the like are often installed on the upper surface of the substrate of the apparatus. However, for example, if the substrate is provided on the upper side of the device, the socket 20
0, 200 ', etc. may be installed on the lower surface of the substrate. Even if the sockets 200, 200 ', etc. are installed on the lower surface of the substrate in this way, there is no particular problem in function.
However, depending on the device, the sockets 200, 2
The orientations such as 00 'will be different. That is, depending on the device, not only the shutter portions 210, 200 ', etc., but also the insertion holes 220, 220', etc. on the back side thereof are turned upside down. Therefore, the user of the apparatus can use the sockets 200, 2
The insertion direction of the plug 100 with respect to
There is a risk of getting lost.

Therefore, in order to eliminate the fear, when the socket of the optical connector is installed on the lower surface of the substrate, the sockets 200 and 200 'of the optical connector are installed on the upper surface of the substrate. An optical connector socket in which the state of the insertion hole on the back side is similar will be described as an optical connector socket according to an eleventh embodiment of the present invention with reference to FIG. FIG. 30 is a diagram showing a socket of an optical connector according to an eleventh embodiment of the present invention, wherein FIG. 30 (A) is a side view, FIG. 30 (B) is a front view,
FIG. 2C is a cross-sectional view, FIG. 2D is a rear view, and FIG.
Is a bottom view.

The socket 200D of the optical connector according to the eleventh embodiment of the present invention basically includes a shutter 210 ′ of the socket 200 ′ of the optical connector according to the eighth embodiment of the present invention, and an elastic body. Portion 230 ', a shaft portion 240' and an insertion hole 220 'are arranged upside down. The shutter portion 210D and the elastic portion 23 are respectively provided.
0D, a shaft portion 240D and an insertion hole portion 220D.

The shutter 210D and the elastic body 23
Even if the 0D and the shaft portion 240D are arranged upside down as described above, the shutter portion 210 ', the elastic portion 230', and the shaft portion 240 'of the socket 200' may be structurally exactly the same. However, the shutter portion 210D has a convex portion 210DD on its back surface.
Is different from the shutter unit 210 '. The convex portion 210DD is connected to a second housing portion 205D described later.
N is a portion that can be brought into contact with the bottom surface of the insertion hole portion 220D included in N, and is provided on both sides of the shutter portion 210D so as to avoid the elastic body portion 230D on the back side thereof. The projection 210DD functions to improve the holding force when the plug 100 is inserted.

The housing part 205D of the socket 200D
Comprises a first housing part 205DM and a second housing part 205DN, and are substantially the same as the housing part 205 'of the socket 200'.

The first housing portion 205DM is substantially vertically symmetrical with the first housing portion 205M 'of the socket 200'. The second housing part 205DN is separated from the housing part 205D by the first housing part 205DM.

The position of Db has been changed to the position of the rear side 250b 'of the element room 250' provided in the second housing 205N 'of the socket 200' with the upside down arrangement.

The plug tip holding portion 229D provided on the back side of the insertion hole 220D is provided with the socket 200 '.
Of the plug 1 longer than the plug tip holding portion 229 '
A notch 229D1 is provided on the lower side of the front surface so that the shutter portion 210D does not come into contact with the longer length while improving the holding force at the time of inserting the 00. The improvement of the plug tip holding portion 229D and the shutter portion 210D is as follows.
It is needless to say that this is not necessarily required in the socket 200D because it is for improving the holding force when the plug 100 is inserted.

The socket 200D thus configured
Is installed on the lower surface of the substrate of the device, the socket 20
When 0 'is mounted on the upper surface of the same substrate as the above-mentioned substrate, the rotation directions of the shutter portions 210D and 210' are the same, and the arrangement of the insertion holes 220D and 220 'is also the same. Therefore, the user of the device can insert the plug 10 into the sockets 200D, 200, 200 'of the optical connector.
The direction of inserting 0 can be a fixed direction.

Incidentally, for example, in the case of the socket 200 'of the optical connector according to the eighth embodiment of the present invention,
Although the shutter 210 can be substantially closed by the shutter 210 ', the plug guide recesses 221' and 221 'are not closed.
